He remained at the Stehlin Oncology Clinic for two additional years and in 1994 was awarded the Houston’s Consumer Choice Award for Health Care Providers as the Physician of the Year. Most recently he was recognized as one of Lane County’s Best Doctors in a survey done by Eugene Magazine.
Dr. Trezona moved to Eugene and opened Cascade Surgical Oncology in 1995. He is board certified and an active member in the American College of Surgeons, the American Society for Clinical Oncology, and other national and international Surgical and Oncology Societies. He has published extensively in the oncology literature. Dr. Trezona is the only Surgical Oncologist between Portland and San Francisco with a focus of comprehensive cancer care. He cares for both the surgical and medical oncology needs of his patients in a personal and compassionate way. This specialized focus draws patients from beyond the Eugene/Springfield area. He sees patients from throughout the Willamette Valley, central and southern Oregon and northern California.
There has been a dramatic increase in recent years in the number of melanoma cases that occur in this country, and especially Oregon. Because of this, Dr Trezona has felt the need to develop a clinic focused entirely on the care of people with melanoma. This has led to opening the Oregon Melanoma Center where he will focus his attention only on the care of people with melanoma.
He is married and the father of 2 daughters. Dr. Trezona relaxes with woodworking, boating, and maintaining a coral reef aquarium.
Diana underwent intense medical training while achieving her Master degree in Physician Assistant Studies and completed several clinical rotations across the country including Pearl Harbor’s Naval base, Scripps Clinic in La Jolla, and Cascade Surgical Oncology. After becoming national board-certified in 2012, she took a position in the Hematology/ Oncology department of the Mayo Clinic in Scottsdale, Arizona. While very thankful for the opportunity, she realized she left her heart and home back in Oregon. She returned to Oregon in September of 2013, where she happily accepted a position at Cascade Surgical Oncology/ Oregon Melanoma Center.
In her spare time, Diana enjoys spending time with her husband, family and friends. She thrives on running and hiking outdoors and never gets tired of the beauty Oregon has to offer.
“I am truly fascinated by all facets of medicine, but am particularly drawn to Oncology because I feel it is an especially rewarding and meaningful place to be. I love that I get to be part of the team at Oregon Melanoma Center, making a positive impact in the lives of others every day I go to work.”
With the many changes in health care over the years the constant that motivates me is the heart of the doctor and staff in realizing that there is more to medicine than treating disease. At Oregon Melanoma Center there is a commitment to being present with the whole person, mind, body and spirit. That’s why I love working here; it challenges me both professionally and personally.
